Creating a SIP Gateway Trunk

Once you have created a SIP gateway trunk group, you can proceed to create individual trunks to this SIP gateway.


	The LinkManager service, which is responsible for linking SIP lines, is automatically installed with the standard version of the SwyxServer software.

The administration of a SIP gateway trunk is handled with the SwyxWare-Administration. Please start SwyxWare-Administration as described in Chapter Registration on SwyxWare Administration. If you are not yet connected to this server, please connect now as described in How to connect to aSwyxServer.

1. Open the SwyxWare Administration and choose the SwyxServer.

2. In the left side of the SwyxWare-Administration window, click with the right mouse button on “Trunks” and select the entry “Add Trunk…” in the context menu.

Enter a name and a short description for the new trunk here.

Select the trunk group here to which this trunk should be assigned.

General settings such as routings, rights and location-specific parameters are specified in the trunk group. You can use "New Trunk Group..." to create a new trunk group, and then continue with the creation of a trunk.

Enter the parameters the SIP gateway (at the present time, only SwyxConnect is available) needs to log onto SwyxServer via this trunk.

The user ID is combined with the realm to create the SIP address (URI).

Indicate whether or not the gateway needs to authenticate itself.

The user name and password are required for authentication.

This logon data must be entered in the same format as when SwyxConnect was configured (see Step (9) in This is how you configure SwyxConnect).

Please enter the Public Numbers to be routed by this Trunk..

To map several individual numbers or number ranges, enter only one number or one range here, and add the others subsequently in the trunk properties (see The "Numbers" Tab).

With the help of the Codec you select how the voice is compressed for transmission. The following options are available:

High compression. A voice connection requires approximately 24kbits/s.

The voice data is slightly compressed. This keeps the packet delay time in the LAN (Local Area Network) to a minimum. A voice connection requires approximately 64kbits/s.

In this case, the special fax protocol T.38 is used, which takes the set-up of the IP network into consideration. A fax connection using T.38 requires approximately 20kbits/s.

Enter how many calls may be routed via this trunk at the same time.

The maximum number of channels available is determined by the codec used and the bandwidth of the connection between the headquarters and branch office.

Enter the name of the computer on which the LinkManager is managed. Use the name of the computer as it appears in the computer properties.

The new Trunk is created, and is available for further configuration.

For information about how to edit the properties of a SIP gateway trunk post-creation, please refer to Chapter Configuring a SIP Gateway Trunk.
